Abstract

A cosmetic composition contained in a suitable carrier comprising at least one copolymer of acrylic or methacrylic acid, an alkyl acrylate and/or methacrylate and an allyl derivative having repetitive units which correspond to the following formulae: <IMAGE> (1a) <IMAGE> (1b) <IMAGE> (1c) wherein: R1 and R2 constitute a hydrogen atom or a methyl radical, R3 constitutes a linear or branched-chain alkyl radical having from 1 to 20 carbon atoms, R4 constitutes -OH, -NHCONH2, or -OCOR5, R5 constitutes a linear or branched-chain alkyl radical having from 1 to 5 carbon atoms, x constitutes 40 to 90 weight percent, y constitutes 8 to 50 weight percent, z constitutes 2 to 25 weight percent, and the sum of x+y+z is from 80 to 100 weight percent. The cosmetic composition is especially useful as a composition for the hair and skin.

       2. The composition of claim 1, wherein said copolymer has a molecular weight of from 10,000 to 50,000. 
     
     
       3. The composition of claim 1, wherein said recurring units of formula (lb) of said copolymer are derived from a lower alkyl acrylate selected from the group consisting of methyl acrylate, ethyl acrylate, propyl acrylate, isopropyl acrylate, butyl acrylate, hexyl acrylate, 2-ethyl hexyl acrylate, octyl acrylate and methacrylate thereof. 
     
     
       4. The composition of claim 1, wherein said recurring units of formula (1c) of said copolymer are derived from the goup consisting of allyl alcohol, allyl acetate, allyl propionate and allyl-urea. 
     
     
       5. The composition of claim 1, wherein x represents from 50 to 85 weight percent, y represents from 10 to 35 weight percent and z represents from 5 to 15 weight percent. 
     
     
       6. The composition of claim 1, wherein said copolymer comprises recurring units derived from the group consisting of: (a) acrylic acid, methyl acrylate and allyl alcohol;   (b) acrylic acid, methyl methacrylate and allyl alcohol;   (c) acrylic acid, methyl acrylate, methyl methacrylate and allyl alcohol;   (d) methacrylic acid, methyl methacrylate and allyl alcohol;   (e) methacrylic acid, methyl acrylate and allyl alcohol;   (f) acrylic acid, ethyl acrylate and allyl alcohol;   (g) methacrylic acid, ethyl methacrylate and allyl alcohol;   (h) acrylic acid, isopropyl acrylate and allyl alcohol;   (i) methacrylic acid, ethyl methacrylate and allyl acetate; and   (j) acrylic acid, ethyl acrylate and allyl-urea.   
     
     
       7. The composition of claim 1, wherein free acid groups contained in said copolymer are neutralized with a base. 
     
     
       8. The composition of claim 7, wherein said base is an organic base selected from the group consisting of monoethanolamine, diethanolamine, triethanolamine, isopropanolamine, morpholine, 2-amino 2-methyl 1-propanol and 2-amino 2-methyl 1,3-propanediol. 
     
     
       9. The composition of claim 1, wherein said copolymer is present at a concentration of from 0.5 to 10 weight percent. 
     
     
       10. The composition of claim 1, wherein said composition has a pH of 5 from 8. 
     
     
       11. The composition of claim 1, further comprising a detergent selected from the group consisting of cationic, nonionic, anionic, and amphoteric detergents or a mixture thereof wherein said composition comprises a shampoo.
